Specification of Letters Patent.

Patented Apr. 29, 1919.

Application led September 26, 1917. Serial No. 193,392.

To all whom t may concern:

Be it known that I, WILLARD C. BRrN'roN, a citizennof the United IStatesof America, and a resident of New York, county and State of New York,have invented certain new and useful Improvements in Mountings, of whichthe following is a specification, reference being had to theaccompanying drawings, forming a part thereof.

My invention relates to a mounting or backing for maps, plans, charts orthe like, and has for one object to provide a backing that shall beparticularly adapted to receive short pins or tacks for the purpose ofgraphically representing predetermined facts.

In representing facts graphically by means of maps, charts or the like,I have employed tacks or pins which may have heads of varying colors,styles or sizes, to represent both the position and the density of linesof troops or the distribution of population, or the extent of sales indifferent parts of the country or the like.

It is particularly desirable to provide a backing into which pins ortacks may be readily thrust and which at the same time will havesufficient friction to grip the tacks near the head and avoid theiraccidental removal.

According to my present invention I provide a simple, durable andinexpensive backing which is light in weight, is relatively stiif, andpossesses the aforesaid advantages.

In order that my invention may be thoroughly understood I will nowproceed to describe the same in the following` specification and thenpoint out the novel features thereof in appended claims.

Referring to the drawings:

Figure l is a plan view showing my improved backing in use.

Fig. 2 is a sectional elevation through a portion of the backing drawnto a relatively large scale and illustrating its construction.

Fig. 3 is a sectional view on the line 3 3 of Fig. 2, and

Fig. 4 is a section on the line 4--4 of Fig. 2.

The backing illustrated comprises a body 10 composed of a lightsubstance into which pins or tacks may be easily inserted. I prefer toutilize a plurality of layers 11, 12 and 13 of corrugated board, theintermediate 'layer l2 being arranged with its cells eX- tendingoppositely from the cells of the layers 1l and 13 to make it stiff.

Mounted on the base 10 is a layer 14 of cork, linoleum or the like whichis adapted to permit the tacks or pins to be forced through it readilybut which at the same time offers suiiicient friction to grip the tacksor pins and prevent them from either falling out or being removed tooeasily.

The cork layer is preferably glued or pasted to the top of the base andit is preferably finished with an outer surface of muslin, linen orother suitable fabric designated l5, to protect it against crumbling ordestruction.

The cloth or paper 16 on which the chart or map is printed is laid onthe linen or muslin surface 16 and the tacks or pins which aredesignated 17 are stuck through the map into the back as clearly shownin the drawings.

Felt may be substituted for the cork layer if desired, and the clothsurface for the cork or felt omitted, although I prefer the structureillustrated.

The cloth layer 15 serves to reinforce the structure and a second layerdesignated 18 is preferably mounted on the back as shown in Figs. 2, 3and 4.-. The cloth may be either single-ply or multi-ply, and the cork,felt, linoleum or the like may be omitted entirely if desired.

The advantages of the use of maps or charts with tacks or pins havingheads of different sizes and color to represent facts graphically havealready become well known and need not be discussed in detail.

The structure of the backing and particularly the materials employed maybe varied within the spirit and scope of my invention, and I intend thatonly such limitations be imposed as are indicated in the appendedclaims.

What I claim is:

1. A backing for maps or the like comprising a cellular base having atopy layer composed of cork, with a surface of fabric.

2. A backing for maps or the like comprising a cellular base having atop layer composed of cork, with a surface layer of cloth stuck thereon.

A backing comprising corrugated board built up in layers with theircells extending alternately in opposite directions and-a sur- 6p Abackingcomprising `a relatively stil?, face member adapted to griptheshank of a light, inexpensive base easily perforated by pm or tack. apin or tack, a sub-surface layer adapted to 4.
